So, I gave it a shot and was able to host WCF services using the BasicHttpBinding on a worker role. The only trick to this was that you needed to not only use the http (as opposed to tcp) port type, but you had to use the HostNameComparisonMode enumeration
and set it to Exact.

I will have to give it a shot. It might be a case of the http versus tcp port choice (http.sys). I have not tried what you are talking about, but I would be interested in seeing if it didn't work. Thanks!

The whole issue with concurrency is to make sure that only one instance is processing the work. The 'golden ticket' approach does not apply to work that can be done in parallel. You would only use that approach when you wanted to ensure that something
was done once and only once in an otherwise parallel environment. Make sense?

@jigneshpandya - In general, you don't set limits. That is, you have some limits like 100TB of total storage (blobs, tables, queues) per storage account (up to 5 accounts by default). Are you asking something else?
